i don't think a warp drive will take a thousand years to achieve. they're already theoretically possible, the only limiting factor was the power source required. originally it was thought that the energy from all the stars in our galaxy would be needed, then with better math it was hypothesized that the equivalent of a single star's energy would work, and now the energy requirement is down to around the
size of Jupiter
given how fast our technology is advancing, with computers that will be thousands of times more powerful than what we have today coming in the next couple of decades, one would think we could figure out space travel in the next couple of centuries if it is possible
